Tianjin Medical Journal 2015;(3):292-295
Objective To explore changes of risk factors between premenopausal and postmenopausal female patients with coronary heart disease (CHD). Methods A total of 283 female patients were divided into CHD group (n=154) and con?trol group (n=129) according to whether they suffered from CHD or not. Patients were further stratified into two groups accord?ing to menopausal situation:premenopausal group (n=78, including premenopausal CHD group of 34 cases and premenopaus?al control group of 44 cases) and postmenopausal group (n=205, including postmenopausal CHD group of 120 cases and post?menopausal control group of 85 cases). Clinical data of age, body mass index (BMI), medical history and menses situation were recorded. The levels of cholesterol (CHO), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), low density lipo?protein cholesterol (LDL-C), very low density lipoprotein cholesterol (vLDL-C), apolipoprotein AI (ApoAI), apolipoprotein B (apoB), lipoprotein a (Lpa), homocysteine (HCY) and high-sensitive C-reactive protein (hsCRP) were also detected. Results There were significantly higher levels of age, CHO, TG, LDL-C, vLDL-C, Lpa, ApoB, hsCRP, and the ratio of hypertension history, diabetic history, coronary heart disease family history in CHD group than those of control group. The level of HDLc was significantly lower in CHD group than that of control group. The ratio of hypertension history, diabetic history and levels of CHO, TG, LDL-C, vLDL-C, Lpa, ApoB, hsCRP were significantly higher in both premenopausal and postmenopausal CHD groups than those of their control groups. The level of HDL-C was significantly lower in postmenopausal CHD group than that of postmenopausal control group (P<0.05). Hypertension history, diabetic history and LDL-C were the independent risk fac?tors of premenopausal CHD. Hypertension history, diabetic history and CHO were the independent risk factors of postmeno?pausal CHD, and HDL-C was the protecting factor of CHD. The ratio of hypertension history, the level of CHO and LDL-C were significantly higher in postmenopausal CHD group than those of premonopausal CHD group. Conclusion The abnor?mal blood pressure level and dyslipidemia are more prevalent in postmenopausal female patients with CHD than premeno?pausal female patients. We should control these risk factors to improve the prognosis.

Literature of TCM contains abundant information of Chinese medicine. Traditional Chinese medicine information is characterized by its high degree of knowledge-intensive and complex inter-knowledge, so it is difficult to integrate and share knowledge. TheShanghanlun is one of the Chinese medical classics, and it includes the rules and methods of syndrome differentiation and treatment and it showed good effects in the clinical application. However, it is difficult to master for beginners. As a kind of knowledge organization tool, topic maps can flexibly define the relationship between knowledge, which realizes the visualization of knowledge network, and integrates and shares the distributed knowledge. This paper focused on the current situation of topic maps researches. The topic maps was used to organize the original content ofShanghanlun, construct the concept model of it and explore the specific application of topic maps technology in the field of traditional Chinese medicine.

OBJECTIVETo dicuss the application and therapeutic effect of middle-forearm flap based on perforator of ulnar artery for electrical burn wound on the wrist.
METHODSFrom Oct. 2009 to Oct. 2012, 10 cases of electrical burn wounds on the wrist were treated. A line from radialis medial epicondyle of humerus to the interior radialis pisiform bone was connected as flap axis. At the midpoint of the line, Doppler flow imaging meter was used to detect the emerging point of perforator vessel. The flap was designed and harvested. The flap was transferred reversely, with superficial vein retaining which was anastomosed with vein at recipient sites in 3 cases. The wounds in the donor sites were closed directly in 2 cases, and with skin graft in 8 cases.
RESULTSAll the 10 flaps survived completely. 7 cases without vein anastomosis underwent obvious flap edema during 2-4 days postoperatively, which resovled 1 week later. Sub-flap tissue necrosis and infection happened in 2 cases, which healed after dressing and drainage. Patients were followed up for 3-36 months with satisfactory results.
CONCLUSIONSThe middle-forearm flap based on perforator of ulnar artery has a stable and reliable blood supply. It offers a new choice for the electric burn wound on the wrist, especially at the ulnar side.

Objective To determine the prevalence of and correlations between HIV infection and syphilis among men who have sex with men (MSM) in Beijing.Methods Totally,600 MSM collected from sentinel surveillance sites for AIDS in Beijing were recruited in this study,and underwent screening tests for HIV infection and syphilis.Enzyme-linked immunosorbent assay (ELISA) was used for the primary screening for HIV infection,and Western blot for its confirmation.Both nontreponemal test (rapid plasma regain (RPR) assay) and treponemal test (Treponema pallidum particle agglutination assay,TPPA) were performed to detect syphilis,and only those with a reactive TPPA result were defined as having syphilis (including past infection).Specimens confirmed as HIV-1 positive were further tested with BED-capture enzyme immunoassay (CEIA) to find recent HIV-1 infection,and the incidence of HIV infection was then calculated.The correlation between syphilis and HIV infection was statistically analyzed.Results Of the 600 MSM,49 (8.17%) had HIV infection,including 14 cases of recent infection,with the incidence rate of HIV infection being 4.68%; 51 were positive for both RPR and TPPA tests with the infection rate (including past infection) being 18.5% (111/600).People without a Beijing household registration and those with high education levels accounted for a large proportion of HIV-infected MSM.Conclusions The prevalence and incidence of HIV infection as well as prevalence of syphilis maintain at a relatively high level in MSM in Beijing.HIV infection is markedly correlated with syphilis in MSM population.

Objective:To test the expression of Minichromosome maintenance complex component 7(MCM7) protein in hepato-cellular carcinoma(HCC) of different species including human, rat and tree shrew (tupaia) by cross-species oncogenomics approach, and to investigate the relationship between the expression of MCM7 and the development of hepatocellular carcinoma and its clinical significance. Methods:Western blot and Immunohistochemistry were applied to detect the expression levels of MCM7 protein in HCC tissues,corresponding HCC-adjacent liver tissues and normal liver tissues collected from different species including human, rat and tree shrew, respectively. The clinicopathologic factors were also analyzed with the results of Immunohistochemistry. Results:Western blot analysis showed that the expression of MCM7 protein in HCC tissues of human and rat were higher than that in corresponding HCC-ad-jacent liver tissues and normal liver tissues, respectively and significantly (P<0.05). However, the expression of MCM7 protein in HCC tissues of tree shrew were also higher than that in corresponding HCC-adjacent liver tissues and normal liver tissues, but no significant difference was found among three types of tissues (P>0.05).There was also no significant difference between HCC-adjacent liver tis-sues and normal liver tissues in three species (P>0.05). Immunohistochemical analysis showed that MCM7 protein was mainly ex-pressed in nucleus of HCC cells, and the positive rate of MCM7 protein in HCC tissues of human, rat and tree shrew were significantly higher than that in corresponding HCC-adjacent liver tissues and normal liver tissues, respectively (P<0.05). However, no significant difference was found between HCC-adjacent liver tissues and normal liver tissues (P>0.05). Moreover, the protein level of MCM7 was intimately related to patient's HCC stage, extrahepatic metastases and postoperative recurrence (P<0.05). Conclusion:MCM7 protein might play a pivotal role in hepatocarcinogenesis. In addition, it was probably related to patient's HCC stage, extrahepatic metastases and postoperative recurrence. It seems very likely that MCM7 may be applied as a new molecular target in HCC prevention and treat-ment.
